According to the integrated double-phase-flow air-dissolving machine, the quality of produced air-dissolved water is good, the water yield is large, the structure is simple and exquisite, the installation, the fixation and the maintenance are convenient and flexible, and simultaneously, the air amount is convenient to adjust.
Description
Technical field
The utility model belongs to the environmental protection equipment technical field, relates to pressure air-dissolving air-float system, relates in particular to the molten mechanism of qi of a kind of integral type two-phase flow.
Background technology
Air-dissolving air-float system, it is a kind of processing mode in sewage flotation treatment process, after being injected in processed sewage after the dissolved air water produced by molten mechanism of qi discharges by reliever, saturated dissolved gas water discharges micro-bubble and upwards floats under normal pressure, in the bubble floating process, take the suspended substance in sewage to the water surface, then utilize the instruments such as scraper plate that suspended substance is removed.
Traditional molten mechanism of qi is actually by subsets such as pressure air-dissolving tank, air compressor, high pressured water circuling pumps and forms, complex structure, and floor space is large, and energy consumption is high, installs, debugs, uses difficulty.
In order to solve the problem existed on prior art, people have carried out long-term exploration, have proposed solution miscellaneous.For example, Chinese patent literature discloses Unitary self sucking effective pneumatic floater [application number: 00237331.9], comprise electric motor, pump and pressure-pot, motor is connected with the upper end of pump by tubular shaft, penstock is connected to the lower end of pump, pump distributes impeller to form by open-vortex impeller and aqueous vapor, and aqueous vapor distributes impeller to be communicated with water inlet pipe and inlet pipe, and water inlet pipe is built in pressure-pot.The problem that this molten mechanism of qi exists is structure or more complicated, most critical be to adopt swirl vanes to make hydraulic part, the dissolved air water generation is little, treatment effect is poor.Because complete machine all is placed in the air supporting casing, installation and maintenance are very difficult in addition.
Addressing these problems is extremely urgent as from the foregoing!
In view of this, the inventor has done deep research to this, designs the molten mechanism of qi of a kind of integral type two-phase flow, and the molten makings amount of generation is good, the water yield is large, exquisiteness simple in structure, and installation, fixing, easy to maintenance flexible, tolerance is easy to adjust simultaneously, and this case produces thus.
The utility model content
The purpose of this utility model is that the dissolved air water quality of generation is good, the water yield is large in order to provide a kind of integral type two-phase flow molten mechanism of qi, exquisiteness simple in structure, and installation, fixing, easy to maintenance flexible, tolerance is easy to adjust simultaneously.
For achieving the above object, the technical solution of the utility model is:
The molten mechanism of qi of integral type two-phase flow, comprise pressure-pot, motor, the hydraulic part be connected with motor, be provided with water return pipeline between hydraulic part and pressure-pot, described hydraulic part comprises centrifugal impeller, and the pump case that is arranged on the centrifugal impeller outside, water inlet at hydraulic part is provided with suction culvert, be provided with the jet head between suction culvert and pump case water-in, inlet pipe and air intake control valve have been located near the jet orifice of jet head, communicate with jet orifice, in the pressure-pot bottom, be provided with the dissolved air water outlet pipeline.
Further, described motor level is arranged on the bottom of pressure-pot.The setting of this structure, be beneficial to the installation and maintenance of motor and hydraulic part, very convenient, flexible.
Further, described motor is submersible machine, is arranged on the inside of pressure-pot.And the hydraulic part connected with it is arranged on the outside of pressure-pot, both separate with air except rotating shaft.The setting of this structure, on the one hand be beneficial to electric motor temperature reduction, can move continuously, and improve motor work-ing life.Liquid in hydraulic part is difficult for entering in motor cavity and damages motor on the other hand, has improved the reliability that equipment is used.
In the utility model, admission passage is arranged on to the front of centrifugal impeller, makes the air entered enter again in dissolving after the pulverizing of centrifugal impeller, make the pressure in dissolving need not the too high dissolved air water that also can obtain high-quality, saved energy consumption.The adjusting of air input is more convenient in addition, also just makes the use of whole molten mechanism of qi more convenient.
The beneficial effects of the utility model: the utility model exquisiteness simple in structure, installation, fixing, easy to maintenance flexible, the dissolved air water of generation is of fine quality, amount is many.Tolerance is regulated very convenient simultaneously.
In order further to explain the technical solution of the utility model, below by specific embodiment, the utility model is elaborated.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
